Failure to comply may cause serious injury.5.1 Shipping contentsRefer to Figures 1 and 2.1 Box and pan brake (not shown)2 Support legs – A1 Curved handle – B2 Straight handles – C1 Stop rod – D2 Counterweight assemblies – E1 Stop rod pin – F1 Stop collar – G1 Hex key, 6mm – H4 Hex cap bolts, M12x40 – HP18 Hex cap bolts, M10x40 – HP21 Flat washer, M16 – HP38 Flat washers, M12 – HP48 Flat washers, M10 – HP58 Lock washers, M12 – HP68 Lock washers, M10 – HP74 Hex nuts, M12 – HP81 Hex nut, M16 – HP91 Cotter pin – HP10Figure 1Figure 2 5.2 Tools required for assembly6mm hex key (provided)pliers5.3 Unpacking and cleanup1. Remove all contents from shipping crate andcompare to the contents list in this manual. Ifshipping damage or any part shortages areidentified, contact your distributor. Do not discard packing material until brake is assembled and operating satisfactorily.2. Carefully clean all rust protected surfaces witha mild solvent or kerosene and a soft rag. Donot use lacquer thinner, paint thinner, or gasoline – these will damage painted surfaces.3. Coat all machined surfaces with a light coat ofoil to inhibit rust.5.4 AssemblyRefer to exploded view if additional clarification is needed for assembly.1. Remove bolts holding support legs and brake topallet.2. Locate brake in a dry, well-lighted area with asturdy, level floor. Machine location must allowroom for loading and offloading stock, and access on all sides for maintenance.3. Use hoist or forklift to carefully lift brake ontosupport legs. Secure with M12 bolts, washersand nuts (HP1/HP4/HP6/HP8).Do not allow anyone beneath brake while moving it into positionand until it is secured on support legs.4. Verify that brake is level; use shims ifnecessary. Secure support legs to floor withappropriate fasteners, such as lag bolts (notprovided).5. Install counterweight assemblies to left andright hinges with M12 bolts, lock washers andflat washers (HP1/HP4/HP6). See Figure 3.Figure 36. Install handles to front of apron (Figure 4).Figure 47. Install stop rod assembly on left side of brake,through weldment on apron, as shown in Figure5. Secure stop rod pin (F) with flat washer andhex nut (HP3,HP9). Install cotter pin (HP10) atend of stop rod, and bend with pliers to secure.Figure 56.0 Adjustments6.1 Counterweight positionProper counterweight position determines amount of leverage for the bend, and most efficient movement of apron for the operator.Adjust counterweight by backing out screw (J, Figure 6) and rotating upper and lower collars (K) as needed. When counterweight is at desired position, turn screw (J) until it re-engages counterweight.Figure 6 6.2 Apron adjustmentThe apron assembly has been adjusted by the manufacturer for use with material having the capacity listed in the Specifications section. If any misalignment occurs, correct as follows.The forward edge of hold-down fingers should be adjusted parallel to pivot edge of press bar. Release clamping pressure on hold-down assembly by pushing clamp handles (L) slightly to the rear. Turn knobs (M) to adjust fingers for parallel.Figure 7The truss nuts (N, Figure 7) can be used to help achieve alignment in apron and hold-down assemblies, by eliminating any bowing at the center of these assembles.Finger alignment can be achieved by loosening cap screws on the fingers, and raising apron to 90-degree position. Push fingers forward against apron bar for proper alignment. Retighten all screws.6.3 Adjusting for metal thicknessThe holddown assembly must be adjusted to allow for clearance when making bends according to thickness of material. Clearance for material within four gauges of the capacity should be twice the thickness of the material. For lighter gauges use 1-1/2 times the thickness.When adjusting for thickness, turn both knobs (M, Figure 7) the same amount to maintain parallelism of fingers with apron.6.4 Adjusting clamping pressure Clamping pressure should be adjusted according to material thickness. Clamping pressure should be great enough to hold material securely in place but not so much that it is difficult to lock clamping handles. Clamping pressure can be adjusted by turning nuts on threaded rod portion of yoke assembly (P, Figure 8).6.5 Repeat bendsAdjust stop collar on stop rod (Figure 5) to limitapron swing.7.1 LubricationThe machine must be lubricated every day ofservice with a few drops of oil at the pivot points. Oilpinholes are located at both yoke assemblies (A,Figure 8) and the apron assembly near the hinge pin(B).Lightly oil all machined (unpainted) parts when notin use, to inhibit rust.Figure 88.0 Replacement PartsReplacement parts are listed on the following pages.

XTENSA处理器调研分解
1.背景介绍1.1.Tensilica介绍Tensilica 是一个迅速成长的公司，公司主要产品是在专业性应用程序微处理器上，为现今高容量嵌入式系统提供最优良的解决方案。
公司成立于1997年7月，该公司的投资者包括三家声名卓著的创投公司：Oak Investment Partners，Worldview Technology Partners 和Foundation Capital，与高科技电子业内著名的五家公司：Cisco Systems，Inc，Matsushita Electric Industrial Company Ltd，Altera Corporation，NEC Corporation 和Conexant Systems。
Tensilica的创始人为Chris Rowen，同时也是第一任CEO，他原来曾任职于Intel，Stanford，MIPS，SGI和Synopsys，同时他也是可重构处理思想的提出者和实践者。
Tensilica公司创立的目的则是提供一种可以实现可重构的、核基于ASIC的、拥有对应软件开发工具的专用微处理器解决方法。
通过前期技术上的发展以及三轮融资，Xtensa处理器诞生了。
图1展示了Tensilica公司创业起步阶段的发展状况：图1：Tensilica公司创业起步阶段的发展状况Tensilica公司于2013年3月被Cadence公司以3.8亿的价格收购，为Cadence 在当时最大的一次收购。
Tensilica公司2012年销售额为4400万美元，收购价超过其营业额的八倍，这也充分显示了Tensilica公司的价值。
1.2.SOC处理器在如今复杂的SOC设计中可以看到有很多种的嵌入式处理器，从通用的处理器到专用的处理器。
通用的嵌入式处理器虽然可以很好的处理各种的控制任务，但当遇到像神经网路处理、基带数据包处理、图像处理、音频处理以及信息加密处理这中复杂的大数据处理时，它们的结构、处理方法以及带宽的限制使其显示出极大地劣势。

电子行业深度研究：人工智能进入新时代，开启算力需求新篇章
电子人工智能进入新时代，开启算力需求新篇章伴随着OpenAI 推出的AIGC 产品功能逐渐强大，由此而带来了新的供给。
AIGC 已逐渐跑通成熟的商业模式，并且模型快速迭代，国内厂商奋起直追，促使整个社会对于算力需求的快速提升。
➢ 伴随着OpenAI 推出的AIGC 产品功能逐渐强大，由此而带来了新的需求。
伴随着AIGC 产品的应用场景逐渐丰富，无论是to B 端还是to C 端，都创造出了新的需求。
➢ OpenAI 已逐渐跑通成熟的商业模式，主要采用按量收费方式。
首先作为底层平台接入其他产品对外开放，按照数据请求量和实际计算量计算。
其次最新发布插件功能ChatGPT Plugins 可以帮助客户访问最新信息、运行计算或使用第三方服务。
➢ 算力需求指数级提升，国产替代随之而来。
伴随着AIGC 模型快速迭代，在模型性能实现飞跃式提升的同时，模型所使用参数量与预训练数据量也呈现指数级增长，与之相对应的便是整个社会对于算力需求的快速提升。
2023年开始美日荷对我国半导体产业链的掣肘行动逐渐加剧，国产算力替代随之而来。
➢ 投资建议：我们认为，AIGC 应用面逐渐越来越广，国内各大厂商奋起直追，整个社会对于算力的需求将呈现指数级增长，叠加美日荷对我国半导体行业的掣肘，国产替代随之而来。
重点关注： ➢ 1）GPU 厂商：景嘉微、海光信息；➢ 2）CPU 厂商：海光信息、龙芯中科；➢ 3）FPGA 厂商：紫光国微、复旦微电、安路科技；➢ 4）AI 芯片厂商：寒武纪、国芯科技；➢ 风险提示：AIGC 行业发展进程不及预期；国内厂商由于起步较晚而无法与国际巨头竞争；国产替代进程不及预期。
