Description

Technical Field

[0001] This utility model belongs to the field of punching technology, and in particular relates to a punching equipment for hollow elevator guide rail connectors. Background Technology

[0002] A punch press, also known as a press machine, is a metal processing device mainly used to stamp metal sheets to form the desired shape or separate workpieces. To improve the safety performance of punch presses, safety light curtains are usually installed on them. These light curtains mainly monitor and control specific areas by emitting and receiving infrared or visible light beams to ensure that operators or objects within that area are not harmed by the machine's movement.

[0003] During the operation of a punch press, oil stains and debris often accumulate, easily adhering to the safety light curtain. This dirt reduces the light transmittance of the light curtain, weakening the light signal received by the receiver. This can prevent the safety light curtain from accurately detecting obstacles during normal operation, thus creating a safety hazard.

[0004] Therefore, it is necessary to improve the stamping equipment in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a stamping equipment for hollow elevator guide rail connectors, which improves the safety of the stamping equipment during operation.

[0006] To achieve the above objectives, the specific technical solution of the hollow elevator guide rail connector stamping equipment of this utility model is as follows:

[0010] Preferably, the sliding sleeve is fitted onto the outer periphery of the mounting rod, and a buffer is provided between the sliding sleeve and the mounting rod.

[0011] Preferably, the buffer includes a rubber ring circumferentially disposed on the inner circumferential surface of the sliding sleeve, and both ends of the rubber ring are circumferentially provided with flange portions, the flange portions covering the end faces of the sliding sleeve.

[0012] Preferably, a support ring is fixedly connected to the bottom end of the mounting rod, and a fixing sleeve is detachably connected to the top end of the mounting rod. Both sliding sleeves are disposed between the support ring and the fixing sleeve.

[0013] Preferably, the fixing sleeve is fitted onto the outer periphery of the mounting rod, and the fixing sleeve is threadedly connected with a locking screw, the front end of which abuts against the mounting rod.

[0014] Preferably, the protective film is continuously wound in multiple layers on the outer peripheral surface of the transparent cover.

[0015] Preferably, each layer of the protective film has an easy-tear line along the extension direction of the transparent cover, and the opposite sides of the two transparent covers are light-transmitting surfaces, with the easy-tear line and the light-transmitting surface being offset.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the stamping equipment and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figure 1-3 As shown, a hollow elevator guide rail connector stamping equipment includes a workbench 101 fixed on a machine body 1. A safety light curtain 201 is installed on the workbench 101. The safety light curtain 201 includes a transmitter and a receiver arranged opposite each other. Both the transmitter and the receiver are provided with a protective mechanism 2. The protective mechanism 2 includes a cylindrical transparent cover 202. Both ends of the transparent cover 202 are sealed with end caps 210. The surface of the transparent cover 202 is also covered with a tear-off protective film 212.

[0027] The aforementioned stamping equipment can be used for stamping and forming hollow elevator guide rail connectors. The safety light curtain 201 is installed at both ends of the workbench 101 near the worker's standing position. The transmitter of the safety light curtain 201 emits an infrared beam to the receiver. When the worker operates, his body passes between the transmitter and the receiver to block the infrared light. In this state, the receiver cannot receive the infrared light. The safety light curtain 201 sends a signal to the control system of the stamping equipment to restrict the start of the stamping equipment, thereby ensuring the personal safety of the worker.

[0028] In this stamping equipment, the transparent cover 202 and the two end caps 210 enclose a sealed space. The transmitter and receiver of the safety light curtain 201 are located inside their respective sealed spaces, thereby protecting the safety light curtain 201 and preventing it from being bumped during loading / unloading or worker operation. This reduces the failure rate of the safety light curtain 210. Simultaneously, the transparent cover 202 protects the safety light curtain 210, reducing the accumulation of dirt and wear, and extending its service life. The protective film 212 set on the transparent cover 202 is colorless and transparent, allowing infrared light to pass through it. The protective film 212 isolates stains from the transparent cover 202. When there are many stains on the protective film 212, the stains can be removed at the same time by tearing off the protective film 212, thereby achieving rapid cleaning of stains on the transparent cover 202, ensuring the light transmittance of the safety light curtain 201, improving the detection accuracy and precision of the safety light curtain 201, and thus improving the safety of the stamping equipment during use.

[0029] Further improvements include, for example Figure 2 and 3 As shown, the workbench 101 is vertically fixedly connected to the mounting rod 203, and the end cover 210 is provided with a sliding sleeve 209 that slides with the mounting rod 203. The ends of the transmitter and receiver are both fitted with sealing rings 211 that are fixedly connected to the end cover 210. The sealing rings 211 are sealed and inserted into the inner side of the end of the transparent cover 202. The sealing ring 211 is used to position the end of the safety light curtain 201 relative to the end cover 210, improving the stability of the safety light curtain 201 installation. A sealing ring is provided between the sealing ring 211 and the transparent cover 202, which ensures the sealing performance between the sealing ring 211 and the transparent cover 202 while also positioning the transparent cover 202, improving the firmness of the transparent cover 202 installation. The sliding sleeve 209 slides along the mounting rod 203, which can adjust the distance between the end covers 210, allowing different models of safety light curtains to be installed between the two end covers. Both the transparent cover 202 and the safety light curtain 201 are inserted into the sealing ring 211, which facilitates the installation and removal of the transparent cover 202 and the safety light curtain 201, improving the convenience of equipment maintenance.

[0030] Further improvements include, for example Figure 2 and 3As shown, the sliding sleeve 209 is fitted onto the outer periphery of the mounting rod 203, and a buffer is provided between the sliding sleeve 209 and the mounting rod 203. The buffer includes a rubber ring 207 circumferentially disposed on the inner circumferential surface of the sliding sleeve 209, and flanges 208 circumferentially disposed at both ends of the rubber ring 207, which cover the end faces of the sliding sleeve 209. Since the punch press generates significant vibrations during operation, these vibrations are transmitted to the safety light curtain 201, impacting it and increasing its failure rate. By using the rubber ring 207 to isolate the safety light curtain 201 from the mounting rod 203, an effective buffering effect is achieved. The flanges 208 are made of rubber, which increases the buffering range and improves the buffering effect. Through the buffering effect of the rubber ring 207 and the flanges 208, the impact force on the safety light curtain 201 is reduced, thereby improving the operational stability of the safety light curtain 201.

[0031] Further improvements include, for example Figure 3 As shown, a support ring 204 is fixedly connected to the bottom end of the mounting rod 203, and a fixing sleeve 205 is detachably connected to the top end of the mounting rod 203. Two sliding sleeves 209 are disposed between the support ring 204 and the fixing sleeve 205. The support ring 204 and the fixing sleeve 205 are used to position the sliding sleeves 209, thereby ensuring a tight connection between the end cap 201, the transparent cover 202, and the safety light curtain 201.

[0032] Further improvements include, for example Figure 2 and 3 As shown, the fixing sleeve 205 is fitted onto the outer periphery of the mounting rod 203. The fixing sleeve 205 is threadedly connected to a locking screw 206, the front end of which abuts against the mounting rod 203. The locking screw 206 is used to lock and unlock the fixing sleeve 205 and the mounting rod 203, thereby improving the ease of installation and removal of the fixing sleeve 205 and the ease of equipment maintenance.

[0033] Further improvements include, for example Figure 4 As shown, the protective film 212 is continuously wound in multiple layers on the outer periphery of the transparent cover 202. By setting multiple layers of protective film 212, each layer of protective film 212 can be peeled off sequentially during cleaning, allowing for multiple cleanings of the transparent cover 202, thereby extending the continuous working time of the equipment and improving its working efficiency. By covering the outer periphery of the transparent cover 202 with the protective film 212 in a winding manner, the layers of protective film 212 form a spirally distributed whole, allowing the outer protective film 212 to position the inner protective film 212, improving the stability of the protective film 212 on the transparent cover 202. Compared with protective films that are individually bonded, its bonding stability is higher.

[0034] Further improvements include, for example Figure 4 and 5As shown, each protective film 212 has an easy-tear line 213 along the extension direction of the transparent cover 202. The opposite sides of the two transparent covers 202 are light-transmitting surfaces, and the easy-tear line 213 is offset from the light-transmitting surface. The easy-tear line 213 facilitates the separation of the contaminated protective film 212 from the entire protective film 212, improving the ease of removing a single layer of protective film 212.

[0035] Further improvements include, for example Figure 2 and 3 As shown, the light-transmitting surface of the transparent cover 202 is a plane. The plane design reduces the refraction and reflection of infrared light emitted by the safety light curtain 201, ensuring the intensity of infrared light transmitted to the receiver, improving the sensitivity and accuracy of the safety light curtain 201, and thus enhancing the safety of the stamping equipment during use.
